This means of knife edges 37 (see Figs. 2 and 15) and aspring 38 is employed to press the shift frame 36 upwards so as tocounter-balance the weight of the front portion 31 of p of the springmay be aid-- justed, lprefer to provide a series of notches, 36 in theshift frame as shown in Fig 15; by engaging the hook In order that theaction and arepress'ed toward the paths of the arms 66 by springs .68.The movement'of the latches may be limited by making them withforkedportions, embracing members 69 of the machine frame; Each shaft 67carries at it's-upper end an arm having aguide '71 for the ribbon 55.'Near each end of the ribbon is seof these notches, the purchase of thespring is varied. cured theusual metal loop or projection-of such a'sizeThe tension of the spring can be varied by engaging either the upper orthe lower opening of'the hook 38' with the frame 36. The tension of thespring 38 may also be adjusted by means of, the screw 38 which holds thelower end of the spring. The mechanism for shift ing the frame '36 forthe writing'of capitals or small characters will be described in detailhereafter.

The shaft 21 of the escapement mechanism is also directly connected withthe ribbon feed devicein the foltion as the shaft during the feedmovement, by a'spring pressed pawl '39 secured to a -3 9 rigid with theshaft 21; These parts correspond to those designated by 21" and 21?,except that the pawls 21 ,and"39 face in opposite directions and thusact oppositely. -.T he pinion 39 meshes with a toothed wheel 40 rigidlycon- -nected with a bevel wheel 41 engaging another bevel 3, 11 andl2)projected frcnu frame of'themachineholds the bevel wheel. 42- "11stlongitudinal movement, and in permanent engagement with the bevel inthesleeve 43 and, in bearings tfi, but is held to rotate tion.'

Near its ends, the shaft 44 carries rigidlytwo bevel-- 49 (Figs. 4 and11); It will-be understood from 11 and 12 :that only oneoff thesets ofwheels 47, 48 is in mosh at a time. Each shaft 49 is in. drivingconnection by means ofbevel gearingSO, 51, with .theshaft'52' of one ofthe ribbon spools 53, contained in the holders 54-. These spools andholders beofthe usual 'cons'truction the ribbon 55 on it's way from onespool to the other passing through a ribbon guide 56 disposed adjacentto:

the. printing point'.'.'; This ribbon guide'receives a rearlever, byvmeans of Meyer 57 (Fig; 1), having a pinand slot connecfion-with thehard? and fulcrumed at 58J ing the ribbon guide 56; the swihging'of-thislever is: limited by a screw (i1, extending through a slot 59; n1. 'Inorder that the direction of the ribbdnieed ma anismis provided (Figs. 1,2, 4 and ll The shaft 44 lars PP-which are adapted to be engagedby'forked push fingers 62 In: -.:rite on shafts anfdfunder theinfluence-' o f springs B51 whi tend to throwmaid' that it cannotpass-through the guide 71. jWhen this loop engages the said guide, thegu ide will be swung aside so as to bring the corresponding nests away.8 from the arm 66. This will release the'shaft 63 and reversing thedirection of, the ribbon. movement. The push fingers '62 are broughtback-to their orig'nial (set) position in any suitable manneflforinstance, by the carrisge-shift mechanism, as fully'describcdhcrcinafter. j i I V.

The tabulating mechanism comprises a key lever- 73v 85 (Fig. 1)connectedby a-link 74 with a rearwardly ex: tending lever 75, fulcrumedat. 76', the .rear end of which operativelyengages a transversellever77, fulcrumedat78 (Fig. 3 This lever is connected with a verticallymovable stepped stop 79 arranged to be projected more-or lessinto thepath of the carriage by' .suita .ble mechanism, jor an ordinary stop(without steps) may be. usedwhn denominational tabulation is notdesired. The stop 79 is adapted for engagement with the stop member 80a; a column-stop .80 (or s'ev'f -l eralof them) mounted .on the rear -81which is :on

' the rear portion 28 of the carriage. Theistop'member- ,0 may-bepivoted to the casing80 ahdghe'ldby a 80" either 'in the operativelower. position adjusting itflengthwise" of the rod, and awe 83 forholding'it after adjustment, said toe ,engaging a rack 84 on the rearportion of the'carriage A spring 85 (Fig; 1.0' throws aha 1186 towa d 5top plate. 87' having a ledge or rib -87'.sothat the casing of thecolumn stop is thrown either toward tlie raclg 84for away from it.

The margin s'tops'may be of almost the same construction as the columnstop, except that the margin stopproper 88 has a limited swingingmovement lengthwise of the rack 84 in the usual manner. The ,sto psadjustable on the rod 81 (whether column stops stops) are preferablyprovided with two pointers 89, 90, .adapted to indicate on the scale 91,

one of such pointers beingfin operative position whether 1 25 thestop isengaged with the rack' 84 or'released therefrom. 3 -1 The release of thecarriage from the cscapement for tabulating purposes is effected bymeans of anarm'9 2l' noui tea't the 11-1 mm 7's oi'the' lever '75 an};in in 113g with said .iThe said arm carries a'roller 93 (preferabl '1;ball bearingslwadapted -to' ,engage a smooth screw 94, per- Thus-atjthefilepressiori-"of the-tabulating key,- the roller 93 will engage therack 27 and release the carriage'by swinging its entire rear portion 2Saway from the pinion 26. Atthc same time the stop 80 will be hrog ghtinto the :path of the stop 79. Furthermore the rack 27'will be'broughtagainst astatio'nary brake strip95.

' The mechanism fer shifting platen portion of the carriage intoposition'for' the printing ofeither small 1:; characters or capitals isas follows! The shift frame 36 (see' Figs. 2,14 and 14'?) is connectedpivotally at both ends by-lugs 36 withlifting bars 96,'pre ferably madein two sections, adjustable by means of screws 96, so that the saidlifting bars may be lengthened or shortened.

The upper portions of said bars have spring members 96? carryingtheconnct ing'pins 96. The lower end of each lifting har has an openingthrough whiclrprojects a pin 97", rnountedeccentr'ically upon a disk 97secured to a shaft 98. This shaft isjournaled. in' the frame by means ofball 'bearings99, an'djalso carries a pinion 100 (see Figs. 4 anjcl14);This pinion is located only at one side-of the machine and engages atoothed sector 101 on a rock shaft 102. This rock shaft at the other endof the machine carries an arm 103 (see Fig; 1). Shift keys 104and 105respectively are adapted to'engage the arm 103 and the arm of the sector101. Tli us by depressing either one of the shift keys the carriage willbe moved to its upper position, but if the shift,irey 104 has beendepressed, the carriage will not retufn to its lower position upontherelease of said shift key, but will be held in its upper positionowing to the engagement of a latch 106 pivoted at 107 with a projection101' on the sector 101. The latch 107 is under the infiuence'of a spring107 and has a beveled surface 107 at the bottom,

40 which su'rfacev is adapted to be engaged by a pin 105 on the shiftkey 105. -Thus if the carriage .is locked in its upper position and itis desired'to release it, the shift key 105 is depressed and the pin105- will swing the latch 106 clear of the projection 101 and allow thecarriage to drop. 'It will of course be understood that if the shift key105 is depressed while the carriage is in its lower position thecarriage will be raised but will drop back as soon as the shift key isreleased, ,owing to the fact that the pin 105 keeps the latch l06'awayfrom the p pin 101, until the latter is about in the position shown 105until the operator re tores the latch to its normal position. p I

I desire to call particular attention to the fact that the eccentricpins 97* reach their dcad center positions when the carriage is in itsupper or its lower printing position, thus locking the shift frame :36against acci dental movement in either printing position.

The carria e shift mechanism is also em )loved for the i lifting bars 96(see Figs. 2 and 14) are provided with original position.

hooks 103, pivoted at 108 adapted to engage the ends of -the amisfififlEach hook 108 is-connect'ed with a spring 108 the upper end of whichslides in a guide l08on the frame of the machine. Thus when the liftingbar 9( i is in its lower position,,the spring holds the' hook in theprojecting position'shown in Fig. 14', but

'as-the lifting bar rises, the hookwill be swung ongits pi'vo't'in thedirection of the arrow to finally cle ar'the arm (SGafterthelatch 65 hasbeen set. Thus'when the carriage is shifted to is upper'position the10815 will engage and raise the arms 66unless these ariris should happen tobe already. intheir upper or set posi tion. The latches 65 ortheportions of the arms 06km; gaging them are of course beveled as shownin Fig-d6, or otherwise so constructed that the latch willibe swung 8 0aside when the arm 66 is raised from its 'lower to its up Per Position.1 I l.j

In order to allow the carriage'to be readily removed, I provide thefollowing construction, sh wn ,in'lfig. 3. l'he frame rod33 on whichthe. carriage moves has at its ends two recesses 33, facing in the'same'direction in which recesses are located pinsj33P, adapted toheengaged by' stationary slotteds'upports 109; carried the frame of themachine. The slots or recesses 33* are somewhat wider than the supports109 so that'the rod can he slid lengthwise to disengage the pins-33 fromthe slots of the supports 109. In order to lock the rod 33 in position,I provide a latch 110 movable vertically to fill the space between oneof the supports 1 09 and the wall of the recesses 33. as shown at theright in 3.- By this construction the carriage can be readily.

removed from the machine, and another harriagecoidifferent widthsubstituted therefor. The following mechanism is employed for lockingthe carriage at the end of a line: The belltri 111 which' is operated bythe right'h'and margin stop (left'hand in f Fig. 3) in the usual way ismounted on the rock shaft 7 113 which also carries the bell hammer 112.After ciearing the hell trip 111, the margin stop willeng'age' 2. lug111 and-tl1us cause the shaft 113 to slide length-- wise. In thismovement the lug 111! swings a lever 114, pivoted at I15, and; providedwith an opening at its lower end so as to straddle the stop pawl 23.Norv mally the lever l14-is inactive; when however the mar-- gin stopswings the lever on' its pivot, said lever takes such a position as tobe in the path of the stop pawl 23 so that the escapement bar 17 .cannotbe moved rearward. The key levers are thus docked. The lever 114 isguided in a slotted-portion 1.16 of the frame.' In order to restore thelever 114 to its original position, I 115 provide a spring pressed key117 which operates a lever 118, fulcrumcd at 119, and having pin andslot connection ,with an arm 113 on the shaft 113. The'lug 111 will thusbe swung out of the path of the margin stop, and as soon as the lug isclear, a'spring 120 (Fig. 6) will 120 throw the lever 11 i and the shaft113 back to their An important advantage is secured by the uso of thepawl 23 pivoted on the machine frame, instead of mounting such pawldirectly on the bar 1 7 as has been done for the pawl 19. By thcarungement shown the carriage-pr:)pelling spring is caused to actuate thebar 17 on its return movement through a much greater path or throw thancould be secured ii the pawl 23 were mounted directly on the har'17.
